Carbon fiber reinforced composites, unlike other FRP composites that use traditional fibers, such as glass fiber or aromatic polyamide fiber, the excellent properties of CFRP composites include:Light Weight -- Conventional fiberglass reinforced composites use continuous glass fibers that contain 70% (glass by weight/total weight) and typically have a density of 0.065 pounds per cubic inch.
High Strength -- Although CFRP composites are light in weight, they have higher strength and greater hardness per unit weight compared to glass fiber composites.Compared with metal materials, this advantage is more prominent.For example, experience tells us that CFRP materials weigh only one-fifth as much as steel at the same strength.You can imagine why every car manufacturer is looking into using carbon fiber instead of steel to improve the performance of their products.
When CFRP composites are compared to aluminum, one of the lightest metals, the basic assumption is that aluminum of equal strength weighs about 1.5 times as much as carbon fiber body.Of course, there are many other variables in the experiment that may affect the comparison results. For example, the grade and quality of the material, the composite process, the production process, the fiber structure and the quality also need to be taken into account.
